In a riveting device, comprising chuck means adapted to receive the mandrel of a blind rivet to exert a cycle of pulling the mandril to set the rivet and break the mandrel and to eject the thus broken mandrel, a means for latching the clutch comprises an axially shiftable member so that the riveting device is latched for a cycle of operation by a simple axial push upon the drive shaft. A bit has a power transmission collar. The drive shaft has a well in which there is a socket. The combination of bit and collar is inserted into the well in the driveshaft whereby the pin and spiral association between collar and socket permit power transmission from the electric drill to the driveshaft. Thus an electric drill having such bit and collar can be used alternately for hole-drilling and power transmission for the riveting device. |
